Question

我试图在节目视图上打开一个职位帖但我得到下面的错误。如果我用find_by替换find它会以某种方式工作，但它只获得活动记录的第一项。

**ActiveRecord::RecordNotFound in JobsController#show**
Couldn't find Job with 'id'=id

模特：

class Job < ActiveRecord::Base
validates :title, presence: true
validates :company, presence: true
validates :url, presence: true, uniqueness: true
end

控制器：

class JobsController < ApplicationController

def index
    @jobs = Job.page(params[:page]).per(12) 
end

def show
  @job = Job.find(params[:id])
end

def new
    @job = Job.new
end

def create
    @job = Job.new(job_params)
    if @job.save
        redirect_to root_path
    else
        render 'new'
  end
end 

 private
    def job_params
    params.require(:job).permit(:title, :company, :url)
  end

end

索引

<% @jobs.order("created_at desc").each do |job| %>

<p><%= link_to job.title, job_path(:id) %></p>
<% end %>

Answer 1

在您看来：

<% @jobs.order("created_at desc").each do |job| %>

<p><%= link_to job.title, job_path(job) %></p>
<% end %>

单击链接时，在JobsController＃中显示Rails ActiveRecord :: RecordNotFound
